[Mailman-Users] Trouble migrating

[Lothar Schilling]

Hi everybody,

today I tried to migrate our whole mailman installation to another server.

Old server: Centos 6.10, Mailman 2.1.29, Python 2.6.6

New server: Centos 7.7, Mailman 2.1.30 (from the tgz file), Python 2.7.5

It seemed to be an easy transition. But then I started to realize I've 
run into problems. For example, I can't release a moderated message. 
Also, I cannot switch users from moderated to not moderated or hidden to 
unhidden. The error logs look like this:

  /usr/lib/mailman/bin/check_perms -f didn't give me any errors.

I also tried to fall back to Centos' standard mailman package which is 
2.1.15 but to no avail.

This took me all day and I'm still where I was in the morning. Any help 
out there?

Thank you very much!
